Prince William‘s younger brother Prince Harry has reportedly called it quits with his girlfriend, lingerie model Florence Brudenell-Bruce, to focus on his military service.

The pair, who have been seen together since June, spent quite a bit of time together over the summer, but the prince reportedly has tunnel vision in achieving his military goals, which limits his time and puts a damper on the romance.

“Harry has a lot on his mind at the moment,” an insider told The Daily Mirror. “He is concentrating on his Apache helicopter training. After that, he’s expecting to return to Afghanistan.

The red-headed son of Prince Charles and the late, great Princess Di will reportedly spend the rest of the year in Arizona, where he’ll continue honing his craft, training as an Apache attack helicopter pilot.
